  • This cross-sectional study included new patients presenting to the University of North Carolina Graduate Periodontology Clinic. Socio-demographic and dental history information were collected. Oral health literacy (OHL) was measured using a dental word recognition instrument Rapid Estimate of Adult Literacy-30 (REALD-30). Clinical periodontal examinations were completed. 128 participants enrolled and 121 completed all study instruments. REALD-30 results indicated 33% had limited OHL (score ≤ 21). 31% had moderate OHL (score of 22-25), 37% had high OHL (score ≥ 26). Mean REALD-30 score was 23 (SD± 4.3). 53% of participants had severe periodontitis, 29% had moderate periodontitis, and 18% had mild or no periodontitis. Bivariate associations were found between OHL and two PHS measures: overall periodontal status (P<0.05) and presence of probing depths (PD) greater than 6mm (P<0.05). The association between OHL and the two PHS measures remained significant in multivariate models controlling for smoking and race.
